[0036] In the actual application process of the power unit structure, the rear end of the module frame 31 in the power component 3 is fixed to the capacitor frame 32, the top of the module frame 31 is fixed to the upper fixed beam 25, the bottom of the module frame 31 is fixed to the lower support plate 26, the front end of the module frame 31 is fixed to the front fixed beam 21, the top of the capacitor frame 32 is fixed to the rear fixed beam 24, the bottom of the capacitor frame 32 is fixed to the lower support plate 26, and the two sides of the capacitor frame 32 are fixed to the two sides of the main frame 1, so that the module frame 31 and the capacitor frame 32 are both stably fixed to the installation structure 2, and the two ends of the lower support plate 26 are respectively fixed to the side fixed lower beams 23 on both sides of the main frame 1, and the two ends of the upper fixed beam 25 are respectively fixed to the side fixed upper beams 22 on both sides of the main frame 1, and the side fixed lower beam 23, the side fixed upper beam 22, the front fixed beam 21 and the rear fixed beam 24 are all fixed to the main frame The main frame 1 is mounted on the support frame 1, therefore, the upper fixed beam 25, the lower support plate 26 and the front fixed beam 21 can support the forces in all directions of the module frame 31, and the lower support plate 26, the rear fixed beam 24 and the main frame 1 itself can support the forces in all directions of the capacitor frame 32, thereby making the module frame 31 and the capacitor frame 32 both stably fixed on the main frame 1, and the module frame 31 and the capacitor frame 32 have corresponding fixation and support at any angle or in the direction of impact force, and finally making the module 311 installed on the module frame 31 and the capacitor pool 32 installed on the capacitor frame 32 stably fixed on the main frame 1, greatly enhancing the connection strength of the power unit structure, and improving the anti-vibration effect of the module 311 and the capacitor pool 321, that is, making the power unit structure able to meet the working conditions of different gravity directions, and having a simple structure and low cost.

[0037] It should be noted that the material used for the main frame 1 is generally preferably a nine-fold profile, which has a more stable and reliable structural strength. Of course, it is understandable that other profiles can also be selected during the actual application process, and no more specific restrictions are made here.

[0038] In some specific implementation schemes, the module frame 31 can be specifically configured as a liquid cooling plate, and the module 311 is arranged on the liquid cooling plate. By designing the module frame 31 as a liquid cooling plate structure, not only can the module 311 be installed, but also the cooling and heat dissipation function of the module 311 can be realized. Of course, it can be understood that the module frame 31 is designed as a liquid cooling plate structure, which is only an example of the embodiment of the utility model. In actual application, it can also be designed as other structural forms, for example, the module frame 31 is only used as an integrated frame of the various components of the module 311.

[0039] It should be noted that the number of the above-mentioned module frames 31 can be designed to be one or more, and when the module frames 31 are designed to be multiple, the rear end of each module frame 31 is fixed to the capacitor frame 32, for example, the module frame 31 and the capacitor frame 32 are fixedly connected by an L-shaped angle plate, and the specific connection method can be fastener connection or welding connection.

[0040] In some other specific embodiments, referring to Figure 1-Figure 3 , the above-mentioned module frame 31 can be fixed on the front fixed beam 21 by fasteners, and corresponding fastener connection holes should be designed on the corresponding module frame 31 and the front fixed beam 21. In addition, the module frame 31 can also be provided with a first connection angle 312 for fixed connection with the upper fixed beam 25 and a second connection angle 313 for fixed connection with the lower support plate 26, wherein the first connection angle 312 is designed at the upper end of the module frame 31, and the second connection angle 313 is designed at the lower end of the module frame 31. By designing into the above-mentioned structural form, the connection and fixation of the module frame 31 is more convenient, the structure is simpler, and the cost is lower. It should be noted that the above-mentioned first connection angle 312 and the second connection angle 313 can be specifically designed in the form of angle steel cooperating with fastener fixing holes.

[0041] In some more specific embodiments, reference Figure 6 and Figure 7 , combined with Figure 3 and Figure 4 The power unit structure may also include two main frames 1, and the mounting structures 2 of the two main frames 1 are arranged symmetrically in the front and back direction. Of course, the power components (i.e., the module frame 31 and the modules 311 mounted thereon and the capacitor frame 32 and the capacitor pool 321 mounted thereon) arranged in the corresponding two mounting structures 2 are also arranged symmetrically in the front and back direction. By designing this structural form, the reinforced fixed support structure of the entire power unit structure has front and back symmetry, and the distribution of the supporting fixing force is more balanced.

[0042] In a further embodiment, referring to Figure 6 and Figure 7 The two main frames 1 preferably share a rear fixed beam 24. The middle part of the rear fixed beam 24 may be designed with a reinforcing member 241, which may be connected and fixed to the top of the main frame 1, wherein the reinforcing member 241 may be, but is not limited to, a Z-shaped reinforcing rib.

[0043] It should be noted that the number of the front fixed beam 21 can be designed to be one or more. Figure 1-Figure 7When there are multiple front fixed beams 21, the module frame 31 can be fixedly connected to at least two of the front fixed beams 21. By fixing the module frame 31 to at least two front fixed beams 21, the fixation of the module frame 31 is more stable and reliable, and the bearing capacity in different directions is stronger.

[0044] It should also be noted that at least one of the six of the front fixed beam 21, the side fixed upper beam 22, the side fixed lower beam 23, the rear fixed beam 24, the upper fixed beam 25 and the lower support plate 26 can be designed to be arranged horizontally. For example, when there are multiple front fixed beams 21, multiple front fixed beams 21 can be arranged in parallel and horizontally. Of course, the front fixed beams 21 can also be designed to be arranged in an inclined manner, such as two front fixed beams 21 are arranged in parallel and inclined, or two front fixed beams 21 are arranged crosswise. In actual application, the arrangement can be selected according to actual needs, and no more specific restrictions are made here.

[0045] In some other specific embodiments, referring to Figure 4 , combined with Figure 1 and Figure 2 The capacitor frame 32 may also be provided with a third connection angle 322 for fixed connection with the rear fixed beam 24, a fourth connection angle 323 for fixed connection with the lower support plate 26, and a fifth connection angle 324 for fixed connection with the rear vertical beams 11 on both sides of the main frame 1. By designing the above-mentioned structural form, the connection and fixation of the capacitor frame 32 is more convenient, the structure is simpler, and the cost is lower. It should be noted that the third connection angle 322, the fourth connection angle 323 and the fifth connection angle 324 can be specifically designed in the form of angle steels cooperating with fastener fixing holes.

[0046] In addition, the utility model also provides a converter, including a power unit structure, wherein the power unit structure is the power unit structure described in any of the above schemes. Since the power unit structure has the above technical effects, the converter having the power unit structure should also have corresponding technical effects, which will not be described in detail here.

[0047] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
